Definition: Quattro Pro
A Windows spreadsheet from Corel that provides advanced graphics and presentation capabilities, including goal seeking, 3D graphing and the ability to create multi-layered slide shows. It is optionally keystroke compatible with Lotus 1-2-3. Quattro Pro was originally developed by Borland, then purchased by Novell in 1994 and Corel in 1996. Quattro Pro was sold as a separate package (Corel Quattro Pro) for a while, but is now part of Corel's WordPerfect Office suites.
